EGG-TURNING TRAY.

Application filed I Tovember 27, 1925.

The present invention is directed to improvements in egg turning traysfor incubators.

The primary object of the invention is to provide a device of thischaracter so constructed that the eggs can be periodically turned in anextremely simple and efficient manner.

A further object of the invention is to provide a device of this kindprovided with a novel form of turning bar which can be operated to turnthe eggs by hand or upon movement of the tray upon a table or othersuitable support.

With these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, in which Figure 1 is a top plan view.

Figure 2 is an enlarged sectional view on line 22 of Figure 1.

Figure 3 is an enlarged fragmentary longitudinal sectional view.

The tray consists of side and end bars, 1 and 2, respectively, ofsuitable wood, there being longitudinal slats 3 having their endssecured to the end bars. A wire mesh screen is supported by these slatsand constitutes a bottom 4: for the tray and upon which the eggs aresupported in transverse rows- Secured to the inner face of each side 1is a metallic plate 6 which extends the entire length of the side. Theupper edge of this plate terminates in a downwardly bent portion 7 toprovide a longitudinal guide groove 8, while the lower edge of saidplate terminates in a flange 9 which rests upon the adjacent slat 3. Theflange terminates in an outwardly bent portion 10 to produce a guidegroove 11. In this manner upper and lower guide grooves are provided forboth sides of the tray, the purpose of which will appear later- In orderto turn the rows of e 's succes Serial No. 71,581.

22 which are spaced from the screen bottom 4 to provide zones 23, intowhich the bar '13 enters after completing its travel from either end ofthe tray. It will be observed. that the endmost rows of eggs will abutthe plates 22, and since the bar can enter either of the Zones, turningof the endmost rows are assured.

In Figure 1 of the drawing I have shown the tray used in connection witha table or other support 24 and upon which the tray may be placed forcooling and turning the eggs thereon at intervals. This table has sides25 provided with stops 26 so that the handles 21 will engage therewithwhen the tray is slid inwardly and at which time the bar 13 will remainstationary and move under each row of eggs to turn the same during suchsliding movement ofthe tray. It will be of, course understood that thehandles may be grasped and the bar slid to turn the eggs, it beingapparent that as the bar is moved it will travel under the eggs with thesand-paper sheet. '15 in a po sition to engage the eggs, thussimultaneously turning all eggsof each row and the rows successively.

What is claimed is 1. An egg turning tray for incubators comprising aframe, said frame having guide grooves associated with its sides, and anegg turning bar having hooks upon its ends slidably engaged with thegroove.

2. An egg turning tray for incubators comprising a frame, plates securedto the side bars of the frame and having upper and lower guide groovescarried thereby, angle members having ribs for slidably engaging theupper guide grooves, an e turning bar having its ends secured to theangle members, hooks upon the ends of the bar for slidably engaging thelower grooves.

tot:

8- An egg turning tray having plates upon its ends to provide zones, andan egg turning bar slidably associated with the frame and movable intoand out or said zones, as and for the purpose set forth.

e. The combination with a support havingstops carried thereby, of an eggturning tray, an egg turning bar slidably mounted in the tray, and meanscarried by the bar for engaging said stops to hold the same stationarywhen the tray is slid upon the support, as and for the purpose setforth.

5. Asa new article of manufacture, an egg turning bar curvedtransversely and having flanges upon its longitudinal edges, a sheet ofmaterial having friction pr0perties engaged upon the convex side of thebar, and retained thereon by said flanges.

In testimony whereof I affix my signature,

JOHN MaoKENZIE.
